CINNAMIC 'ALDEHYDE OZONID.

Specification of Letters Patent.

Patented Feb. 10, 1914..

Application filed May 12, 1916. Serial No. 560,765.

My invention relates to that class of chemical compounds known asozonids, or compounds containing ozone in direct combination.

In a former application, Serial No. 560,764, filed May 12, 1910, I havedescribed a new compound formed by the direct union of pinene in theform of vapor and ozone,

the resulting compound being an ozonid composed of solid particles insuspension.

The object of this'invention is a formation of an ozonid by combiningozone with an aldehyde in the form of vapor by simply intermingling withit ozone or ozonized air, and the further. object of this invention isto produce a non-poisonous, non-irritating,

unite with cinnamic aldehyde highly germicidal Vaporous substance.

The inventor has found that ozone will directly forming an additionproduct. There is no by -product, no splittingv up of either of themolecules taking part in the reaction; the two molecules unite whollyand directly. The reaction is,

The exact structural formula has not been determined, but the union ofthe ozone mole cule with the aldehyde molecule undoubtedly takes placeat the point of double bonding between the two CH groups. The structuralformula of cinnamic aldehyde is,

and the resulting oxidation product would be-- o-cn t I f)-CH This isevident because the oxidation could not take place in the C H groupwithout the splitting off of hydrogen and the formation of water as aby-product of the reaction. The only vulnerable point, the only pointwhere union can take place without any splitting up, is-at the point ofdouble bonding between the two OH groups. Ozone does not unite in thismanner with other aldehydes in which this double bonding does not occur.The resulting compound is an opaque white vaporous substance which ismade up of solid particles of almost molecular fineness in suspension.It does not condens'e or settle on surfaces even at very lowtemperatures and may be conveyed through pipes to long distances. Vhenit emerges into free air it diffuses and assumes an invisible gaseousform without dissociation. It is a true ozonid in a. vaporous'form andpossesses powerful oxidizing properties. It may properly be termed theozonid of cinnamic aldehyde, or cinnamic aldehyde ozonid. &

This ozonid is highly germicidal and this fact has been determined bythe inventonby a series of bacteriological tests. The Bacillusstaphylococcus, B. Streptococcus, and B.

Uoli are quickly killed when suspended in its vapor. Even when the vaporis highly diluted the bacilli are destroyed in less than one hour. It isof a pleasant aromatic odor and is non-poisonous and non-irritating tothe mucous membranes. It can be inhaled in its concentrated form withoutirritation. These facts have been determined by tests extending overlong periods of time.

p The method I preferably employ in its manufacture or generation is inall respects similar to that described for the manufacture of pineneozonid in my application No. 560,764, the apparatus being the samechlorid or slaked lime for extracting the moisture from the air; D is avaporizing ves-. sel for cinnamic aldehyde or cinnamon oil; E is anozone generating device; and F is a diffusing or combining vessel forintermingling the cinnamic aldehyde vapor and the ozone; G is anelectric transformer by means of which an ordinary low voltagealternating current is raised to voltage sufficiently high to operatethe ozone generating device E. I find that from 8,000 to 10,000 volts;are most suitable. In case the available electric current is of thedirect type it is necessary to interpose in the line an electricconverting machine I, such as a rotary converter or dy'namotor toconvert the'direct current into the alternating.

In making cinnamic aldehyde ozonid, C is charged with fused calciumchlorid, and D is filled with sufficient cinnamine aldehyde to present amaximum evaporating surface. The valve J on the pipe C, between G' and Dis closed, and valve K on the pipe between C and E is opened. The fan isnow started and the high tension electric current switched into theozone tube. This causes a current of dry air charged with ozone to passthrough pipe 0 into the combining chamber E. The valve J may now be opengradually allowing the air to pass through the vaporizing chamber D. Thearea of the surface of cinnamon oil in D is'so large that the airpassing atall times will be fully saturated. and the quantity ofcinnamic aldehyde vaporized will be in direct ratio to the air passingover. its surface. The amount of" airrpassing through the vaporizingchamber is gradually increased until the ozone is completely neutralizedor combined "with the aldehyde. "This point can be detel-mined exactlyby testing the escaping cinnamic aldehydeozonid by means of potassiumiodid and starch for free ozone.

From H the outlet ofthe combining chamber H the white vapor of thecinnamic aldehyde ozonid may be allowed to escape freely into the roomor may be conducted to a distance. I

Cinnamic aldehyde ozonid consists of molecularly fine solid particlesthat float freely in the air but it does not settle or deposit on 'asurface. It has a high vapor tensionand assumes the form of a true gaswithout dissociation. I't iscapable of converting water into hydrogenperoxid and is highly germicidal and ispleasantly respirable.

I do notclaim herein the process of producing gaseousyozonids broadly,having made such subject-matter the basis of a separate applicationfiled by me December 2, 1911, Serial No. 663,602, and I also do notclaim herein the apparatus for producing gaseous ozonids illustratedherein diagrammatically, having made the same the subjectmatter of aseparate application filed March 11, 1912,' Serial No. 683,118.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is:

1. The new substance cinnamic aldehyde ozonid havjing the formula (3 110 composed of solid particles in suspension, and being white and opaque.

2. The method of making ozonid of cinnamic aldehyde which consists ingenerating ozone at one point, forming the vapor of cinnamic aldehyde atanother point, and subs'equently combining the ozone and cinnamicaldehyde vapor at a third point.

3. The making of ozonid of cinnamic aldehyde which consists inintermingling the vapor of cinnamon oil and ozone.

1. The process of producing cinnamic aldehyde ozonid which consists incommingling a vapor of cinnamic aldehyde; and ozone out of contact withthe body of said cinn amic aldehyde. a
